RESUMO
AIM: To establish a dry eye mouse model of iron overload by intraperitoneal injection of iron dextran and preliminarily explore its possible mechanism.METHODS: A total of 40 male C57BL/6 mice(taking the right eye as the experimental eye)were divided into 4 groups by random number table method: There were 10 mice in the control group, each time by intraperitoneal injection of 0.2mL of normal saline; Low-dose group, middle-dose group and high-dose iron group with 10 mice in each group were the model group. Each time, 0.2mL of iron dextran solution with concentrations of 12.5, 25, and 50 mg/mL was injected intraperitoneally. One injection 3d for a total of 28d. We observed the ocular surface inflammation index, corneal fluorescein staining, tear break-up time(BUT)and Schimer I test(SIt)on the 7, 14 and 28d after injection and evaluated the degree of dry eye and ocular surface inflammation. After 28d, the mice were sacrificed for cornea, conjunctiva and lacrimal glands tissue for HE staining, Prussian blue staining and tissue iron detection, to evaluate the inflammatory reaction and iron overload. The expression of inflammatory factors interleukin-1β(IL-1β), tumor necrosis factor-α(TNF-α)and matrix metallo proteinase-9(MMP-9)were detected by enzyme-linked immunosorbent assay(ELISA).RESULTS: Compared with the control group, the mice in the model group showed a series of dry eye symptoms, the inflammation index of ocular surface in mice were increased, the score of corneal fluorescein staining increased, the BUT shortened and the amount of tear secretion decreased(all P<0.05). The cornea, conjunctiva and lacrimal gland tissues of the mice were damaged to varying degrees, the iron deposition on the eye surface of the model group was more serious than that of the control group, and the iron content of the tissue was significantly increased than the control group(all P<0.01). The contents of inflammatory factors(IL-1β, TNF-α, MMP-9)in the cornea, conjunctiva and lacrimal gland tissue of the mice in the model group were significantly higher than those of the control group(all P<0.01). With the increase of injection time and concentration of iron dextran, the degree of dry eye and ocular surface inflammation in mice gradually increased. CONCLUSION: The mouse iron overload dry eye model was successfully established by intraperitoneal injection of iron dextran, the mechanism may be related to the ocular surface inflammation aggravated by iron overload.

RESUMO
Traditional Chinese medicine has a long history, unique system and perfect technology, which has been used to prevent or treat a variety of diseases in the form of compound medicine. Recently, some of the active ingredients from Chinese medicine were found to have self-assembly properties, mainly through non-covalent interactions, including π-π stacking, electrostatic interaction, hydrogen bond and coordination interactions, etc. Carrier-free nanoparticles based on self-assembly of active ingredients from Chinese medicine could not only improve the solubility of insoluble active ingredients, but also the bioavailability. As nanocarriers, the natural active ingredients could exert synergistic therapeutic effects. The strategy of self-assembly without carrier is safer and almost non-toxic compared to the commonly used nanocarriers. In addition, some ingredients from Chinese medicine could coordinate with metal ions to form stable nanoparticles, which could be applied to photothermal therapy. In this paper, we summarized and analyzed the recent achievements of carrier-free nanoparticles based on self-assembly of active ingredients from Chinese medicine, and briefly outlined the future development of this kind of nanomedicine.

OBJECTIVE@#To observe the therapeutic effect of herb-separated moxibustion combined with budesonide nasal spray (rhinocort) on moderate to severe persistent allergic rhinitis (AR) of kidney- deficiency type, and to explore the correlation between nasal temperature and condition of allergic rhinitis.@*METHODS@#A total of 70 patients with moderate to severe persistent AR were randomized into an observation group (35 cases) and a control group (35 cases, 3 cases dropped off). Both groups were treated with rhinocort, one spray on each side of the nostril (approximately 64 μg each spray), once in the morning and once in the evening, for 4 weeks. On the basis of the above treatment, the observation group was treated with herb-separated moxibustion at Shenshu (BL 23), Feishu (BL 13), Zhiyang (GV 9), Dazhui (GV 14), 3 moxibustions per acupoint, a single treatment lasting about 30 min. This treatment was given once every other day, 3 times every week, and totally continuous 4 weeks. The changes of AR symptom visual analogue scale (VAS) scores were observed before and after treatment and at 3 months follow-up after treatment. The heat variation (temperature, range) on projection areas of the nose, lungs, large intestine and kidneys of the two groups' patients before and after treatment were detected by the infrared thermal imaging diagnostic system, and the correlation between the VAS scores and nasal temperature before and after treatment was analyzed. The clinical effects of both groups were evaluated according to the VAS score.@*RESULTS@#The total effective rate in the observation group after treatment was 85.7% (30/35), which was higher than 71.9% in the control group (23/32, <0.05). After treatment and at follow-up, the VAS scores of both groups were lower than those before treatment (<0.05), and the VAS score of the observation group was lower than that of the control group at follow-up (<0.05). After treatment, the nasal temperature, pulmonary range, large intestinal range and renal range of the observation group were all lower than those before treatment (<0.05), the nasal temperature and nasal range of the control group were lower than before treatment (<0.05), and the reduction of nasal temperature, nasal range and renal range in the observation group was greater than that of the control group (<0.05). Before and after treatment, there was a correlation between VAS score and nasal temperature (<0.05).@*CONCLUSION@#The herb-separated moxibustion combining western medication has a better effect and long-term effect than western medication alone for moderate to severe persistent AR, which can improve heat variation on projected areas of the nose, lung, large intestine and kidney of patients. In addition, nasal temperature can reflect the severity of the symptoms of patients with moderate to severe persistent AR, or it can be used as a secondary indicator to evaluate condition of AR.

RESUMO
Real world clinical diagnosis and treatment activity is a complicated decision-making task. The effective clinical cases of traditional Chinese medicine (TCM) of highly experienced physicians play an important role in the routine diagnosis and treatment and the formulation of medical knowledge . Based on TCM electronic medical record data, this paper proposed a decision support prototype system on TCM clinical diagnosis and treatment based on TCM effective clinical cases and case-based reasoning (CBR) algorithm, which is used to assist inexperienced clinicians to make more reliable clinical decisions, and thereafter to improve the clinical curative effectiveness. The system integrates TCM clinical cases data set from a TCM clinical data warehouse, and retrieves the similar cases based on CBR method. In particular, according to the underlying personalized diagnosis and treatment for patients in TCM, this system implemented a flexible diagnosis and treatment modification mechanism based on correlation analysis among symptoms, diagnoses (syndrome or pattern in TCM) and medicine. Finally, through a demonstration of clinical application, we made an initial evaluation of the usefulness and practical effects of the system.
